I will present a paper at the AES 138th International Convention in Warsaw/Poland, taking place May 7-10, about head tracking for mobile headphone usage.

Surprisingly, we were also able to show with a subjective test that random head fluctuations, not related to actual head fluctuations, give a similar effect, but weaker.
